Most people have trouble determining the gender of their iguana. It's not easy! Prism_Wolf had a great pic of male femoral pores and hemipenal bulge. The second photo was taken by Ursula to demonstrate female femoral pores. Thankyou ladies!!
My iguana, who is about 5 months, has very definitive femoral pores, but I can't really tell what sex type of pores they are. When do the hemipenal bulges first show up? what about the fat bumps behind the head?
Iguanas are either small dragons or dinosaurs... I'm not sure which, but both are equally cool ; )
